To all whom t may concern:

Be it known that l, JOHN ELTON DnZnLL, a citizen of the United States, residing at Quincy, in the county ot' Gradsen and State oi' Florida, have invented certain new and useful Improvements in a Circular Glass Cutter7 of which the following is a speciication.

rllhe present invention relates to unprovements in glass cutters and more particularly glass cutter oi the circular type. The main object of the invention is to provide a circular glass cutter which is read adjustable both horizontally and vertically, to compensate *for the varying thicknesses or glass, in the first instance, and to permit adjustment olf the cutter wheel so that pieces ot glass oi difierent diameters may be cut. A `t'urther object oi the invention is to provide a device of the character set forth above which is simple in construction, cheap to manufacture and convenient to operate.

A still further object oi the invention is to provide means whereby ready access may be had to the cutter wheel at all times to facilitate the changing of the wheel should occasion so require. i

Various other objects and advanta es of my invention will become apparent during the continuance ot the following description.

'ln the drawings Fig. 1 is a view in invention as in its preferred embodiment.

Fig. 2 is a detailed view. ln reducing my invention to practice l first provide a support 10 which may be con structed of any suitable or desirable material. r)The support carries an arm 11 which extends at substantially right angles with respect thereto and preferably horizontally with respect to the floor or other base (not shown). A brace arm 12may also be employed to aid in supporting the arm 11 in a rigid position, the. arm 12 being connected with the support 10 and the arm 11 as clearly shown in F' The outer end oi the arm 11 is journaled in the collar 13 of a vertically disposed sleeve 14: the latter being open at its upper and lower end and extending both above and below the arm 11. lt is pointed out that screw thread connection may be had between the arm 11 and the sleeve la and more particularly between the arm 11 and the collar 13. However this construction is merely collateral to the main invention and do elevation showing my carrying not. wish to limit myself to its use or application.

i kvrod 15 extends through the sleeve 14rand is substantially longer than the sleeve in order to permit the slidable movement thereof. A head 16 is formed at the upper end ci' the rod to limit movement in one direction with respect to the sleeve and another head 17 is carried at the lower end of the rod and may have screw threaded connection therewith. lt is pointed out that while the main purpose ot the head 17 is to carry the glass cutting device and to permit adjustment thereot, it also serves to limit the upper movement of the rod as is obvious upon reference to the drawings.

rlhe head or bloclr 17 is provided with a transverse slot or opening 18 and another opening 19 at right angles to the lirst named opening. rlfhe cutting rod 20 is positioned through the transverse slot or opening 18 while a thumb screw 21 is positioned in the opening 19 in order to retain the cutting rod in rigid relation to the head 17 and the rod 15 and yet permit a ready adjustment thereof. Suitable graduations may be placed on the cutting rod 2O as shown at 22 and a lrnob or handle 23 is positionedat one end thereot whereby it may be swung about the sleeve 14- which acts as a pivot. u

@ne end oi the cutting rod 2O may be provided with'a depending finger 24: tor the cutting implement 25, the latter being positioned slightly below the plane ot the cutting rod 20 will be observed upon reierence to the drawings. .it is contemlated that the cutting implement 25 be readily moveable 'tor the purpose ol substitution or repair.

ln operation the thumb screw 21 is loosened so as to permit adjustment o' the rod 2O to the desired dimension after which the thumb screw may be tiehtened to hold a rod in a rigid relation to t e rod 15. rlfhe cutting implement heilig engaged with the plate of glass, the operator may grasp the knob or handle 23 so as to swing the rods 20 and 15 about the sleeve 14rat the same time exerting a slight pressure on the knob or handle so that the cutting implement will score the glass in a circle ci the desired diameter.

What is claimed is A glass cutting device comprising a supporting structure, a ltube supported thereby, a rod projecting beyond the tube at both knob or handle on the upper side, said rod ends and adjustable therein, one end of the sion spaced from, extending below und rod being headed, a slotted head at the othel` end of the rod7 a Cutting element, a carrysaid cutting element In said extension, said 10 lng rod adjustable in the slot of the said he Said ead and enlarged at one end to provide a In testimony whereof I nfiix my si "nature being bent inwardly to form a finger exten- Y l l J.
